SLOMO

Material for SLOMO performance prediction framework presented at SIGCOMM 2020

Hardware & OS

We use two machines for our experiments, one for hosting NFs and another for traffic generation. Below we describe two such hardware setups.

Setup 1

  • CPU: Intel Xeon E5-2620 v4

  • NIC: Intel XL710 - 40GbE QSFP+ 1584 (2 NICs/server)

  • OS: Ubuntu 18.04.3 LTS - 4.15.0-99-generic

  • DPDK: 18.05.1 stable

  • NIC Drivers: i40e-2.9.21 - iavf-3.7.53

Setup 2

  • CPU: Intel Xeon Silver 4110

  • NIC: Mellanox MT27700 Family [ConnectX-4] 1013 (2 NICs/server)

  • OS: Ubuntu 18.04.2 LTS - 4.15.0-48-generic

  • DPDK: 18.11.1 stable

  • NIC Drivers: MLNX_OFED_LINUX-4.5-1.0.1.0-ubuntu18.04-x86_64

Note:

  • Each port on the generator is directly attached to the corresponding physical port of the testing server.
  • Ideally, both machines should be dual-socket with high core count processors. Hyper-threading should be deactivated.
  • The specific driver NICs were necessary to ensure that DPDK would work seamlessly on top of SR-IOV.

Installation - Setup

  • setup/ contains sample setup commands for partitioning the NIC with SRIOV.

  • experiment_scripts/ contains sample scripts that initiate NF experiments

  • data_processing/ contains sample routines for parsing experiment data

  • traffic_generator/ contains a sample traffic generation script

  • The NFs we used in our work rely on DPDK for I/O.

  • Please ensure that your NIC’s VF drivers are updated and that a compatible version of DPDK is being used.

  • Please ensure that NFs will be spawned on cores of the same CPU socket as the NIC they will be receiving traffic from to avoid unnecessary communication over QPI.
